I have a general question that is probably simple: Our house has a private well and we have both a softener and a filter. It seems that everytime we have to shut the water off at either the main shutoff (after the pressure tank) or at the pressure tank, the water is rusty and hard when we turn it back on. This seems to last an inordinant amount of time. The most recent example was due to the fact that we had to replace some piping and valves for our utility sink and washing machine. The work was done and the water was turned back on before the filter and softener cycles started that night. The filter cycles every night and the softener cycles every other night. They have both run at least twice since we turned the water back on, but the water is still hard and rusty. Why does this happen?? Thanks for the info.
